摘 要:
在地震记录反演中,盲目反褶积是一个相当困难的问题。讨论这个问题现有各种方法,如累积矩法等。本文利用Likas等处理图像恢复的变分法来讨论地震记录反演中的盲目反褶积问题。利用Kullback-Liebler信息测度获得一个非常有用的统计函数(即变分函数),此函数的极值点就含有所要求的反射系数序列的信息,并且拟订出求此泛数极值点的一套算法。[著者文摘]

Kullback-Liebler Measure Applied to the Blind Deconvolution

Abstract:
In the inversion of the seismic,to solve the problem of a blind deconvolution is pretty difficult. There arc various methods to discuss this problem,such as the method of the cumulant moments etc. In the paper, the problem of a blind deconvolution in the seismic is discussed by the functional method,by which Likas etc study the problem on the restoration of an image. A statistical function (i. e. the variational function) ,the maximum point of which includes the information of the reflective coefficient sequence,is obtained by using the Kullback-Liebler inforrnation measure,and the algorithm is devised for computing the maximum value of the variational function.[著者文摘]
